Temperature

The advent of December reveals an average high-temperature of a still tropical 31.5°C (88.7°F), showing minimal difference from the prior month. During December, the temperature is averaged to a low of 21.8°C (71.2°F) at night.

Heat index

In December, the average heat index is computed to be a torrid 36°C (96.8°F). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.
Heat index details are generally centered around shaded locations and a mild breeze. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', comes about by integrating the temperature readings with the humidity levels. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
